useful Improvements in Cleaners for Spinning-Machines, of which thefollowing is a specification.

This invention relates to cleaners forspinning machines of the kindshown in my U. S. Patent No. 1,129,312 of February 23, 1915, and theobject of my present invention is to improve certain hereinafterdescribed parts of said cleaner and its actuating mechanism.

The cleaner shown in my said patent comprises endless cords, travelingin one direction only and carrying wipers'which traverse thethread-boards, roller-beams, backboards and creels of the spinning frameand detach lint and other foreign matter therefrom. Each cord is guidedby suitable pulleys and is weighted with a uniform tension to keep itstraight and to cause it to. move with uniformity in one direction in afixed path. The wipers or brushes remove the lint, etc.,' from thespinnino frame', which lint adheres not only to t he wipers and brushesbut also to the cords and in order to clear the wipers and cords'fromlint, etc., 1

adhering thereto brushes are provided which engage the cords and wipersanddetach the lint, etc., therefrom.

In my patented cleaner the cords extend over one end of the frame andthe weights are applied to vertical portions of the cords and the cordsare driven by pulleys mounted on a shaft actuated from the main shaft ofthe machine whichpulleys are arranged below the plane of thethread-boards, rollerbeams and back boards, and loops are formed in thecords which extend downwardly around the driving pulleys and also acrossguide pulleys. Y

I have found that where a large number of pulleys are employed to guideand drive the cords considerable -wear is produced which lessens thelife of the cords and according to my present invention I provide meanswhereby the number of guide-pulleys may be reduced and-the drivingmechanism much simplified. I have also so organized the cleaner that thecords may beshifted to one side when the thread-boards are raised duringdofiing or at other times. In order to prevent the cord-weightsortension devices from swinging or moving out of proper operativeposition I have provided guides for the weights which, while permittingthem to move vertically, hold them against any swinging movement and Ihave provided meansfor holding the cords and their wipers in closecontact with the brushes so that lint, etc., may be effectually removed.

As stated in my patent above mentioned the cleaning cord is preferablymade of cotton and preferably the cord consists of two strands of cottontwisted together. The wipers are preferably made of pieces of cloth suchas flannel and I' have found that where metallic fastenings are used toattach the wipers to the cord the thread-boards, etc., are considerablyworn by such metallic fastenings. In order to overcome this I attach thewipers to the cords by untwisting the strands .sufliciently to permitthe wipers to be passed between them and then again twisting the strandsto tightly hold the wipers. This I' find to be a secure way of attachingthe wipers to the cords and no other fastening device is necessary,although preferably the-leading edge of the wiper is attached to thecord by a single stitch.

Other features of 'my invention will be hereinafter described.

lVhile my improv'eiiients are especially in tended for use in spinningmachines, they may of course be applied to other similar cate thethread-boards, B the roller-beams, B theback-boards and O the creel. The

Each of the thread-boards is provided G. which extends-around a pulley gatone end of the'frame which spreads the, cord into two parallelmembers, and at the other end of the frame the cord extends over pul-'leys g and from thence downwardly across the end. oftheframe where theloop formed thereby supports a weightedpulley H. As

usual, each thread-board l3 is'hinged to a roller beam B as indicated atb, and while the pulley g normally overlaps the thread- .board provisionis made, as will-be hereinafter described, for movingthe pulley later-;ally away from the threadboard so that the latter maybe lifted duringdofling and at other times; The cord G carrieswipers or cleaners m whichare held. close to the thread-board by the cord and operate to cleanthis board as well as the roller beam and back board.

Each of the thread-boardsand its associated roller beam andback-board isprovided with a cleaner, as indicated in Fig.1, and the creel C' isprovided with a similar cleaner. The cord I for the creel passes arounda pulley I at one end of the, frame and over pulleys i at thejopposite.end of the frame. These guide pulleys are arranged to properly. spreadthe cord-and from thepulleys i the loop of the cord extends downwardlyover a weighted pulleyJ. I, I

Experience has demonstrated that the often swing laterally to such anextent as .tointerfere with the efficient operation of the cleaner andto overcome this I have prothe axle thereof. Each leg of the bifurcatedweight is formed with 'a vertical. slot 71. which receives a bearingblockh? in which the axle 72, of the pulley rests. Each weighted pulleyent r 1g idQ 0 able way. v

which may be boltedto the faetory floor, or

Each guidebox is provided with a stop H which limits the upward movementof the 'weight. The guide boxes may be, made in various ways but arepreferably so constructed that the pulleys extend throu h vertical slots71. in the opposite sides of tie box. I

.I do-not. limit myselfto the particular formof weight guides shown asthe same result may be accomplished-by other means.

Rotary brushes M, M, are. mountedto rotate on one of the end framesandto engage the vertical portions of the cords G and I. These brushesmay be driveniin any suitable way,.preferably by means of belt .gearingN driven froma pulleyfn on ashaft 7 O which-shaft may be vdriven inanysu'it- ",AS shown in Fig. 2 the wipers are attached to the cordwithout the use-of mtallicfastenlngs. The cord employed preferablyconsists of two strands, and in order to attach a wiper the strands areuntwisted sulficiently to allow the wiper to bepassed through between.the strands. then'the strands are again twisted, asshown in Fig. 2, andthis serves .to securely attach the wiper to the cord.

For additional security however I mayattachithe'front or leading end ofthe-wiper to the cord by a single. threadolj' stitch X asshown inordertoprevent theleading end of-the wiper frompilingup or slipping back and.tl1us' forming a lump or knot which would ;.prev.ent: a proper drawingcontact iw th' e v s pu ey.- I

weighted pulleys shown in my prior "patent 'As before stated eachthread-board .hinged to itsjadjacent roller-beam and asgit ice pulley 9may be moved to one side when it is'necessaryto raise" thethread-board." I ac.- .COl'IlPllSll this by passing the pivotK oftlie.pulley 9 through a slotin therollenbeam and through the armlc of abracket K which is connected .by a threaded stud k 'to an adjustable.vertically arrangedbracket- K at tachedto oneofthe end pieces A ofthe machine frame. Devices .k 'are employed for adjusting the bracket .K.vertically,-; and the lconnection between the bracketsvK' andLK; .l Ssuchthat the bracket K may-be turned to a limited extent in such manneras to move the pulley g laterally away from the ion Z meshing with'a,beveled pinion .Z on a shaft L mounted in'bearings in the bracket K andthis shaft carries a sprocket wheel Z connected by a chain Z with asprocket wheel Z on a shaft 0 which in practice is the front flutedsteel drawing roll which drives the back and top rolls of the set ofdrawing rolls. The shaft 0 carries a spur-wheel 0 geared by the train ofwheels 0, 0 0 0*, 0", 0 to theshaft- P which is the driving shaft of themachine and on which is mounted the band cylinder P" extending along thewhole length of the frame by which the spindles F (Fig. 3) on both sidesof the frame are driven through the bands 79. The shaft L on theopposite side of the machine is in like manner driven by a sprocketchain Q through the gearing shown which is of usual construction andneed not be described in detail further than to Say. that the shaft 9 isthe front fluted steel drawing roll which -drives the back and top rollson that side of the machine. where it is located. The construction issuch that the pulleys g are rotated at the properspeed to drive thecleaning cords, when the thread-boards are lowered or when the machineis in operation. When it is desired to raise the thread-boards thebrackets K may be turned in the manner indicated in Fig. 5 so that thepulleys and cords are out of the way of the thread: boards. In practice,however, each cord and pulley will automatically swing into or assumethe position shown in Fig. 5 as the lower or outer edge of the pulleycomes in contact with the thread-board while the latter is being raised.WVhen the thread-board is released. or lowered the cord and pulley willbe automatically brought back to working positions by reason of the factthat the cord is held at all times under tension by its weight. In orderto support the inner ends of the brackets K at the desired elevation Iprovide lifting devices R each comprising a stem 1" which is threadedand carries nuts T which may be adjusted to hold the bracket K andconsequently the pulley g in the desired plane.

The pulley I which guides and drives the cleaning cord I for the creelis secured to a vertical shaft .9 mounted to turn in a bracket Sadjustably secured to the end frame piece A. The lower end of the shaftcarries a beveled pinion s meshing with a corresponding pinion s on ahorizontal shaft S mounted to turn in bearings in the bracket S andcarrying outside the frame piece A a sprocket wheel T connected by a.chain t with a sprocket wheel 25 on a stud U carrying a. spur orintermediate gear V meshing with the wheels Q and 0'. In this way thepulley and the cord I are driven from one of the intermediate gears ofthe train of gears in the front drawing roll drive.

By my present improvements the devices for cleaning the cords and wipersis made;

more eflicient inasmuch as the cords. and

wipers. are held close to the brushes and the weighted pulleys areprevented from swingng away from the brushes. The threadboards can bevery easily raised during;

dotting and at other times, it being only necessary to move the pulleysg sidewise and inward to a small extent so that they with the outersides of the cords are moved out of the way of the thread-boards.Further-i more, the pulley g and the cord G are so arranged that theymay be moved sidewise and inward automatically in the manner beforedescribed. These pulleys g constituteguides for the cords and alsodrivers therefor and;

receive motion from the usual mechanism employed for driving the drawingrolls. By comparing my present improvements with the mechanism shown inmybefore mentioned patent it will'be seen thatthe driving,
